Tropical Bulbs Tuberoses

Gladioluses, Tuberoses, Cannas, and Caladiums, come under this head, and

are the best known of this class of bulbs. They are not hardy, and the

slightest frost will injure them more or less. It is customary to allow

tender bulbs of this kind to rest during the winter, the same as one

would an onion. They can be safely kept through the winter under the

staging of the green-house, in a dry, frost-proof cellar, where there is

plenty of light, or in any other place where potatoes can be safely

stored. Tropical bulbs of all kinds are much benefited by planting them

in good, light, loamy soil, well enriched with well-rotted stable

manure. They may be planted out in the open ground as soon as it can be

worked in the spring, and all danger from heavy frosts is over. Any of

the above named bulbs of ordinary size, should be planted at least from

three to four inches deep, and from six to eight inches deep when the

bulbs are of extra size. I am in favor of planting these bulbs in the

open ground much earlier than most gardeners are in the habit of doing.

Experience has shown me that the earlier in spring those summer bulbs

are set out in the open ground, the better. Just as soon as the ground

is in good condition to work, spade it up deeply, and plant the bulbs;

the roots will soon begin to develop in the cool ground, before the tops

start to grow, which is the true principle in growing all plants. They

will thus receive a fine start before hot weather sets in. We have had

Tuberoses and Gladioluses to bloom much earlier than usual, and much

more continuously throughout the summer and fall, as the result of

planting them as soon as the ground can be worked in the spring. If a

continuation of bloom is desired, the bulbs should be planted at

successive intervals of not less then three weeks; this will give a

sucession of bloom throughout the entire season. In the fall remove the

bulbs from the ground as soon as the tops have been touched by frost,

cutting the stalk off to within a couple of inches of the base, and

setting the bulbs away to rest for the winter.
